To all whom it may concern: Be it known that I, CAMPBELLYC. CARPEN- ran, a citizen of the United States. residing at Niagara Falls, in the county of Niagara and State of New York, have invented new and useful Improvements in Storage-Battery Practice, of which thefollowing is a specification. The-present invention relates to storage battery practice.

More particularly the present invention relates to storage battery practice whereby batteries. ma be shipped or stored in a charged con ition and retain their capacity .for a long period.

in object of the present invention is'to provide a method of operating storage batteries whereb said storage batteries may be stored or s ipped without the electrolyte and in which the capacity will be maintained i may be added to for long periods.

A further object .is to provide a method of storage battery practice which is simple in operation and inexpensive.

Further objects will be apparent as the a description proceeds.

According to the present invention, the storage battery is preferably brought up to full ity to determine when charge is complete. The electrolyte is then removed from the jars and the battery cells and contents thoroughly, washed with pure water. In the case of small batteries, the Water may be poured into the jars without removing the plates, the water allowed to remain for a few minutes and then pouredout. Several washings of this kind should be given, after the lastof which, all of the water should be allowed to drain 'fromthe cells. In the case of large batteries with heavy plates, the

lates, separators and other contents-may he removed from the cells, the cells washed 1 out and the plates and other parts thoroughly washed in water. After the cells and plates have been allowed to drain thor, oughly, the plates and other parts are re placed in the cells.

After the plates and cells have beet: thoroughly washed with water and allowed to drain. the cells should be thoroughly sealed. Parafiine. or any other referred sealing compound may be used. c sealing .should be very thorough to prevent charge'in any preferred manner, the electrolyte being tested for its specific grav 'by Letters.

access of air to the interior of the cells. Itisimportant that the electrolyte be-thoroughly washed out, otherwise the action of the electrolyte on the plates may-result inthe evolution of gases, resultingin an explosive mixture. Instead of remaining in a free state, the acid of the eletrolyte will 'act upon the sponge lead of the negative plates,- forming sulphate and liberating hydro en. Therefore, not only will the electro yte result in the evolution of a dangerous gas, but will discharge the cell to a greater or less extent, depending upon the amount of acid present in the cell.

. After the cells have been sealed, they may be shipped or stored for long periods, retaining a very great percentage of their original capacit When, it is desired to put the cells into service, electrol of the specific gravity corresponding to ll charge the cells and the cells will perform in the proper manner.

The above described process may be varied in certain particulars, which variations however, will not depart from the spirit of the invention. It is intended that this patent shall cover all modifications that come within the scope of the invention as defined by the appended claims. 1

What I claim as new and desire to secure I Patent of the United States, is

1. The method of operating storage batteries which consists in bringing a battery approximately to a state of full charge, washing the electrolyte from said battery and tightly sealing said battery to prevent the access of air thereto.

2. Storage battery practice which consists of charging a. cell, removing the electrolyte, rinsing the interior of said cell and its contents and tightly sealing said cell.

3. Storage battery practice which consists of charging a cell, removing the electrolyte, rinsing the interior of said cell and its con tents withwater and tightly sealing said cell.

4. Storage battery practice which consists sealing said cell to prevent the access of air.

5. Storage battery practice which consists of thoroughly washing out the electrolyte from the interior of the cell and contents of a substantiallycharged battery and tight- 3 ly sealing said cell to prevent access of air.

6. Storage battery practice "whereby battery cells mejfbe transported or stored in cherged condition without electrolyte, which consists in charging a cellnntil a predetermined specific gravityfof [the electrolyte is reached, thoroughly wbi'shing but the-electrolyte from the "interior of said cell and contents, sealing said cell, and 'when it is desired to put the cell into service again, adding electrolyte of said predetermined specific" gravity.

7. Storage battery practice which consists of hringingfe battery cell to full charge, eliminating sn'bstantially all the electrolyte of a predetermined 'f 8. Storage battery practice which consists of bringing a battery cell to full charge, washing the cell contents with water to remove the electrolyte, preventing access of air to said contents and, when it is desired to use said cell. adding electrolyte ofpredetermined specific gravity In Witness whereof, I have hereunto subscribed my name.
